PROBLEM TO BE SOLVED: To completely exhaust gas, by reducing leaking-out of an injected resin, in a variable pad used for filling up a void generated between a tie plate and a rail arranged on a track slab, when laying the rail on the prestressed concrete track slab and a sleeper.SOLUTION: This variable pad fills up the void under the rail 8 by hardening resin, by injecting the curing-resin inside in a state of being arranged under the rail 8. The variable pad 1 is composed of mutually oppositely arranged plastic sheets 2 and 2 of fusing the periphery except for a part being an injection port 3 of the resin. An exhaust hole 4 is formed in a position near the periphery except for the injection port 3 for exhausting the air existing between the plastic sheets 2 and 2 when injecting the resin.
